I read this article on the BBC today, thought it was pretty interesting

But what about my dear friend Sir Patrick Moore? I joined up with him a couple of weeks ago and was not entirely convinced he was the great astronomer.

His profile said he was here for "random play" and "whatever I can get" and his home town was Pinner.

I happened to know that Sir Patrick lives in Selsey, in Sussex, so I wrote seeking reassurance.

"It is definitely me," he replied some days later, "extraordinary as it may seem! I was told about Facebook by some young camera crew I was working with, you see, and I was intrigued how people are able to communicate these days.

"You're quite right I do live in Selsey, Pinner is the town in which I was born."

I signed up to Facebook just to view a photo gallery but then immediately got sucked it. It lasted a week or so and now I don't care but based on its purpose, it's much better than MySpace and Bebo IMO.
